No response from Nedbank Credit Card division.

On 18 May 2023 I paid an amount into my Nedbank credit card account. In error I used the incorrect credit card number as a reference. The number that I used referred to an old credit card. I contacted various avenues with very little or no response. On 27 May I went into the branch at Keywest Krugersdorp. I provided the consultant with all my details, including the proof of payment. The consultant scanned all documents in and emailed to the CC division and told me that the funds will be credited to my account within 2 days. I have had 2 phone calls since from Nedbank with no success. Please assist as this is beyond frustrating.
